Be it Known that 1, JOHN EDWIN PEDER- SEN, a. citizen the United States, residing at Hillsboro, Montgomery Count Illinois,- have invented anew and useful It achine for Charging. Furnace Retorts, of which the following is a' specification.

This invention relates to machines for charging: furnace retorts with ore.

An object of the invention is to provide an efiicient machine for mechanically charging the retort s of ore furnaces;

Another'object ofthe invention is to provide a machineofthecharacter and for the purpose'mentioned, which is capable of ad justmentand operation to fill or charge all of the retorts in the series.

Another object of "the invention is to provide a machine for charging ore furnaces, comprisingmechanism for throwing the material intotheretorts and improved means for delivering the material to said mechanismf A Another object ofthe invention is to pro? vide a novel and eflioientmechanism for conveying the material to'the machine.

In, the drawings, 7

Fig, 1 is aside elevation of the machine with parts of the hopper or chute in section andbroken away. a

Fig. 2 is an outer side or end elevation.

shown, my invention comprises a car or truck 1, arrangedjto move upon the rails 20m track running parallel withthe charging end of a furnace.

The car or truck 1 supports a pair of rails 3, extending transversely of the truck 1, and having abutments 1. at their inner and outer ends. The frame of the machine comprising the up: rightmembers 5 is op'eratively supported on the rails 3by wheels 6. By this arrangement and construction, the entire machine, including the truck 1, may be moved along the track 2 to serve the dilferent vertical tiers of retorts A; and the machine proper may be moved upon the track 3 transversely of the truck 1 toward" and away from the ends ofthejretorts. Theprovisionfor outward movement of the machine proper on the track 3 is to permitthe machine to be adjustedto pass the fixed projectingtportions. of the furnace. Movement of'the machine on the track 3 is stopped'andllimited to-theabutments l which, as shown, may comprise up turned ends-of the "rails. The

'provided with rollers operating iwithin the"- machine may be moved'in either direction upon the track 3 by any. appropriate device, asby a lever 7 pivoted to a bracketS on the machine frame and having"a connection 9f witha stationary part of the track or support, Whereby'proper operation ofthelever;

will move themachine towarjdor'away from" the ends of the retorts. The lever? is preferably equipped with a latch'device' 10 for engagement with the bracket 8 in, the ob vious manner shown in order to iholdthef machinerigidly inany of its different ad justed positions.

' The frame of the I machine I which, as i stated, comprises the upright member 5 sup ports and guides for vertical'movement a frame-11. The shaft ofa motor 12 mounted; at; the-vertically adjustable frame 11 is belted'to a pulley 13, attached to a shaft :14 in said frame 11. One onmo're balance wheels 15 are attached to theshaft' 14. A link 16' for each of the. balancewheels" 15 has one end pivoted'thereto, eccentrically. of

the axis of the wheel, and the opposite "end of said lever or'levers being-pivoted'to the upper endor ends of a lever orlevers 17. The levers 17 are pivotallysupported inter mediate of their ends'upon supports 18. The lower ends of each of the'le'vers 17*have slidingpivot-al connection, 19 with a shovel or thrower 20. The shovels'o'r throwers 20: are operatively supported upon appropriate tracks carried by the adjustable frame 11. andin' the formshown, comprising channel bars 21', adjustablysupported upon a shaft 22in the vertically Vadjustable hframe 11. The shovels or" throwers- 20'have' arms 23 extending at the sides of'the tracks" 21' and channels of said tracksi From the foregoing it is apparent that" the motor 12 rotatesthefshaft lhavinn 'the balance wheels 15 attached theretofjandthat the connections from saidbalance wheels oscillate the lovers 17 with'th'e' resultth'at the shovels orotliro'w'ers 20 are'operated onthe tracks 21 toward and away"- from 5 the Chara; in}; ends-oftheTret-orts *Morje'ov'er, the moveriient;- area-tr shovels? or throwers to ward the charging -endsf of the retorts is very rapid, the] momentunr-being sufficient.

to throw the material from the :Shovels' or throwers to the inner ends of} the ratens when the *shpvels orj tl ronierstare suddenly stop'ped'ne'arthe endear-the rabies-x Fi'g l 20 to serve the retorts A, irrespective of.

the varying angles of inclination of the retorts. As shown, the outer ends of the tracks 21 are supported by an adjusting device, comprising a shaft 24: having threaded support in the frame 11 and having its lower end pivotally connected with the tracks 21, as shown in 25, Fig. 1. It is obvious that by turning the shaft 2 1 in proper direction the angle of inclination of the tracks 21 may be varied.

The material is delivered to the shovels or throwers through a chute 26 provided for that purpose. The chute 26 is of telescopic construction, the upper section thereof being within a hopper 27 rigid in the main frame 5; and the lower section of the chute is supported by the vertically movable frame 11, so that the position of the frame 11 determines the length of the chute. lVhen the frame 11 is raised within the main frame 5 the length of the chute is shortened by telescoping the sections of the chute 26 in the well-understood manner; and when the frame 11 is lowered in the main frame 5, the chute is lengthened. The result is that the discharge end of the chute is in the same position relative to the tracks 21 at all times. This provides for the proper discharge of the material into the shovels or throwers 20, irrespective of the positions of the reto-rts that are being served by said shovels or throwers.

The lower section of the chute 26 has a. passagefor each shovel or thrower 20 in the machine (Fig, As stated in the specific embodiment of the invention shown, there are two shovels or throwers 20 so that the lower section of the chute is arranged to discharge material from two outlets, one for each of said shovel or throwers. A rotary valve device 28 is in each discharge outlet. The device 28 may be of any appropriate construction, and as shown, each of said devices comprises four vanes or wings extending radially from a rod or shaft 29. By turning the shaft or shafts 29, the discharge control devices 28 may be operated to discharge material from the chute 26. Provision is made for operating the discharge control devices 28 to discharge material from the chute when the shovels or throwers 20 are below the lower end of the chute. Each end of the shaft 29 pivotally supports a bifurcated lever 30. Each lever 30 supports a pawl 31 which is springpressed into engagement with a ratchet wheel 32, adjacently supported in rigid connection with the shaft 29. As the levers 30 are pivotally supported on the shaft 29, they may be moved in one direction without turning said shaft; but movement of said levers in the opposite direction causes the pawls 31 to turn the ratchet wheels 32 and thereby the shaft 29 to operate the discharge devices 28. The outer end of each shovel or thrower 20 has an upwardly extended. part 33which when the shovels or throwers are moved to position under the lower end of the chute 26, pass under the inner arms of the levers 30 and engage the lower arms of said levers 30, thereby actuating said levers to operate the discharge control devices 28 with the result that material is discharged from the chute into the shovels or throwers. The dis charge devices are arranged to discharge only the desired amount of material at each operation. Inward movement of the shovels .or throwers 20 engages the extended portions 33 thereof with the inner arms of the levers 30, thereby restoring said levers to the I throw material from the shovels or throwers to the inner ends of the retorts when the shovels or throwers are suddenly stopped near the ends of the retorts.

The frame 11 may be raised and lowered by winding or unwinding achain or coupling 34, appropriately connected with the frame 11 and passing over sheaves or pulleys 35 to a winding drum 36.

The

Material may be conveyed into the hopper by an endless conveyor device 39 arranged to convey material. from. a car 38 and to discharge the material into the upper end. of said hopper. Thecar 38 is connected and moved with the truck 1. The conveyor shown is of the endless belt type of familiar construction.

From the foregoing it will, be seen that my invention satisfactorily and efficiently serves all of its intended purposes. The material is automatically discharged into the shovels or throwers as an incident vof the operation thereof. The operation of the machine is comparatively rapid and the machine may be made to serveone or more vertical tiers of retortssimultaneously as desired.

l do not restrict myself to unessential features or limitations since it is apparent that the invention may lie-widely varied without departure from the nature or principle thereof.
